1. the books will be more likely to
fall over the slower you pull out the pillow
2. I tried a 5 pound book and did it 10

3. the clips danced and bounced around
like the rice one
4. the kernals vibrated and moved also
The benefit of measuring the initial rate of a reaction V0 is that at the beginning of a reaction: changes in [S] are negligible, so [S] can be treated as a constant.
